(54) Hetero-polycyclic aromatic compound


(57) A novel hetero-polycyclic compound of the following formula, a method for its preparation and its use in the colouration of textile materials:

wherein,

Z, & Z2 are each independently - 0 -, - S - or - NR5 - in wich R5 is H or an optionally-substituted hydrocarbon group or an acyl group;

X1 & X2 are selected from H, halogen, cyano, C1-4-alkyl, C1-4-alkoxy, aryl, carbamoyl, sulphamoyl, carboxylic acid or carboxylic acid ester;

R' to R4 are each independently selected from H, C1-4-alkyl, C1-4-alkoxy, C1-4-alkenyl, halogen and the group -X-Y ;

X is - 0 - or - S -; and

Y is a group of the formula:

wherein:

V & W are each independently H or optionally substituted alkyl;

p is an integer from 1 to 3;

q is 0 or 1 ;

p + q is at least 2; and

Z is OR6 or NR6R7 when q = 1; or

Z is OR8 or SR8 when q = 0;


wherein:

R6 is selected from optionally substituted alkyl, optionally substituted alkoxyalkyl and a second group represented by Y in which R6 is optionally substituted alkyl or optionally substituted alkoxyalkyl; and

R7 is selected from H, and optionally substituted alkyl;

R8 is selected from optionally substituted alkyl, optionally substituted alkoxyalkyl and acyl,


provided that, the substituents on rings A & B are different when Z1 & Z2 are the same or that Z1 & Z2 are different when the substituents on rings A & B are the same.
